IMPROVEMENT IN APPARATUS FOR FILLING OIL-CANS.

To all whom it may concern:

Be it known that I, ELI F. WILDER, of L0 w- Massachusetts, have inventedan Improved Apparatus for Drawing Liquids and Filling Small Vessels; andI do hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawing making part ofthis specification- Figure 1 being a plan of the apparatus; Fig. 2, afront elevation thereof; Fig. 3, a side eleof the same.

Like letters designate corres in all of the figures.

The object of my invention is more particularly to draw oil from largecans or tanks into small cans or oilers with facility and withoutoverflowing them; but it is applicable to drawin g other liquids in likemanner. I

Let A represent the tank, can, or reservoir pondin g parts a pump fordrawing the'oil therefrom into the oilers or small cans. In order tofill the oilers with the greatest expedition it is desirable that asingle stroke of the pump-piston should accomplish the filling; but todo this properly a uniform quantity should be drawn at each stroke. Myapparatus is provided with a gagestroke, which not only draws a uniformbut a definitely-measured quantity of oil, and the measure is changeableand adjustable at pleasure. The mode of effecting the measuredgagestroke of the pump-piston, as shown in the drawing, is as follows:The piston-rod a of the pump is secured to or connected with a slidingrack, 12, into which a stationary pinion, 0, gears. A vibratory movementis given to the pinion c by a lever, (1, whereby the strokes of thepiston are produced. It is evident that by placing limits to thereciprocating movements either of the handle-lever (I, the pinion c, therack 12, or the piston-rod a, a gaged stroke can be produced. Thus, asrepresented, the ban dle-lever (1 moves in a slot, f, the extent towhich it can move therein being limited in one direction by a pin, g,inserted across the slot in any one of a series of gage-holes, h h. Thepinion 0 is shown ection, t, which, in one djustable stop, j; or a uckby a stop, I, adjustas having a pin or pro direction, strikes an astationary pin, k, is str able on the pinion. The rack Z) is representedwith an adjustable stop, on, to strike a stationary part of the frame;and the piston-rod a is shown with adjustable stops it n to strike thetop of the pump. Any of these stops may be provided with a scale toindicate exact measurements. The same principle applies if other meansare employed to communicate the movements to the pump-piston. Thus, if avibratory lever is connected directly with the piston rod the adjustablestop may be applied either to the lever, to the piston-rod, or to both.

There is, however, a difficulty in the practical use of a gage-fillingstroke arising from the fact that the oilers are frequently brought tobe refilled before they are entirely emptied, so that when a quantity ofoil sufficient to fill an empty oiler is pumped therein they overflowand waste oil, as well as become besmeared therewith. To obviate thisdifficulty 1 connect with the filling-pump another pump for completelyemptying the oilers before refilling them. Such a pump I haverepresented at (J in the drawing. This pump is secured upon the tank A,and is constructed so that it will return to the tank the oil pumpedfrom the oilers. This pump is provided with a project ing nozzle ortube, to reach down into the cans or oilers; and a pipe or passage, 1',is represented as extending therefrom down into the chamber below thestationary valve .9, Fig. 2, of the pump, so that the upward stroke ofthe pump-piston draws the oil from the oilers. The oil thus drawn intothe pump is raised to near the top of the pun1p-barrel, and flowstherefrom through a pipe or passage, 1, into the tank. In the drawingthe piston-rod of this pump is shown connected with areciproeating rack,a, which gears into the same pin ion a that operates the filling-pump,the movements of one pump thus alternating with those of the other; or,if other means of operating the two pumps together are a simplevibratory levertheir pumpingstrokes in ay alterna te. In using the twopumps together I effect a great convenience in filling the oilers by theuse of a single nozzle or spout, 12, both for emptying and filling theoilers, so that, when once inserted in them, they do not require to beshifted from their position till they are emptied and refilled; Iaccomplish this, as represented, by connecting the single employedas bynozzle 12 with a pipe, 11, which communicates with both pumps; and bythe use of a stopcock, to, so constructed that by turning it one waycommunication is opened'between the nozzle and the emptying-pump and cutoff from the filling-pump; and by turning the cook the other waycommunication is opened between the nozzle and filling-pump and cut offfrom the emptying-pump. Thus, then, when the movements of the pumpsalternate, the motion of the operating-lever one way empties the oilersand its motion the other way fills them, the stop-cock, in the meantime,being turned.

A single pump might be constructed to both empty and refill the oilers;but more movements would be required, and therefore the operation wouldbe less simple and convenient than the two pumps with one nozzle andalternating in action.

The stop-cock w, arranged as shown, is operated separately by hand; butit may be connected with the operating movements of the pumps, so as tobe turned automatically there- VVhat I claim as my invention, and desireto secure by Letters Patent, is-- I 1.
